Fig. 204. — Diseased stem of Vaccinium in a 

 later stage than Fig. 203. In each epidermal 

 cell (a, a) six mother-cells have been formed, 

 each subdivided into four teleutospores. 

 Promycelia (6) have developed from many of 

 tbe latter, and are in process of abjointing 

 ofE the sporidia from lateral sterigmata.

This aecidium is also found on Aiies cephalonica in Upper

Barclayella deformans Diet.^ This has been found in the Himalaya 

 region on needles and young twigs of Picea Morinda {Smithiana). Teleuto- 

 spore-sori are developed, accompanied by distortion of the host. Aecidia 

 and uredospores are unknown.
